chore: update changelog for 0.7.4 release

Update the debian changelog to reflect the changes included in the 0.7.4
release. This includes listing the bug fixes and refactoring efforts
that went into the release, providing a clear record of the changes for
users and maintainers. The changes include fixes for build failures on
Arch Linux, heap-use-after-free issues, Qt private module inclusion for
Qt 6.11, build problems when examples are enabled, and the removal of
branch filters for workflow triggers.

Influence:
This change does not directly affect the application's functionality.
However, it improves the package information and history, which aids in
debugging and maintenance. After the release, verify the changelog is
accurate and accessible through the package manager or documentation.
Ensure build and runtime issues addressed in this release are resolved
by black box testing on the targeted operating systems, especially Arch
Linux.

chore: 更新 0.7.4 版本的更新日志

更新 debian 的更新日志以反映 0.7.4 版本中包含的更改。 这包括列出版本中包
含的错误修复和重构工作，为用户和维护人员提供清晰的更改记录。 这些更改包
括修复 Arch Linux 上的构建失败、堆释放后使用问题、Qt 6.11 的 Qt 私有模块
包含、启用示例时的构建问题以及删除工作流触发器的分支过滤器。

Influence:
此更改不会直接影响应用程序的功能。 但是，它改进了软件包信息和历史记录，
有助于调试和维护。 发布后，验证更改日志是否准确，并且可以通过软件包管理
